Nonlinear coordinated control of generator excitation and SVC in multi-machine power systems using energy-shaping method

Using interconnection and damping assignment-passivity based control (IDA-PBC) method, this paper investigates the coordinated control of excitation and static var compensator (SVC) in multi-machine power systems. By using Hamiltonian function method, energy-shaping approach and IDA-PBC method, a nonlinear coordinated controller of excitation and SVC is constructed. The proposed coordinated controller can adequately use the physical characteristic of the power system to change transformation of energy between the electrical and the mechanical dynamics. Simulation results verify that the proposed coordinated controller can effectively improve the transient stability and voltage regulation performance of power system.
